The plans are being designed to construct the connection, but it is a very complex project that involves the railroad and the US Corps of Engineers because of the affect on protected wetlands in the area. Before the project can proceed, the City must apply for a permit from the Corps, and the permit needed requires anywhere from 12-18 months or more to be reviewed by environmental scientists. Please check the montly report under Engineering Services on the Frisco website for routine updates. Link:
